Description
This alarm evaluates the unbalance of the phase to phase voltages, i.e. the
difference between highest and lowest phase to phase voltage at any given time.
The following setpoints are related to it:
Voltage Unbalance BOC (page 232)
adjusts the maximum allowed
difference between the highest and lowest phase voltage at any given time.
Voltage Unbalance BOC Delay (page 233)
adjusts the alarm delay.

Description
The overcurrent alarm is based on IDMT principle. The reaction time of an IDMT
alarm is not fixed, but depends on how much is the protected value (generator
current in this case) above the limit (
). The higher is
the overcurrent, the shorter the reaction time will be. All generator phases are
evaluated.
The behaviour of the overcurrent alarm is adjusted by the following setpoints:
IDMT Overcurrent Delay (page 229)
defines the reaction time of the
protection when the current is twice the amount of nominal value.
set the nominal current level, where the
alarm starts to be evaluated. The reaction time is infinite at this point.
